Specification of Letters Patent.

Patented May 25, 1915.

Application filed September 3, 1914. Serial No. 860,071.

T all whom it may concern.-

Be it known that I, ISAAC M. SCHWAB, a citizen of the United States,residing at Savannah, in the county of Chatham and State of Georgia,have invented certain new and useful Improvements in Eyeglass- Guards,of which the following is a specification.

This invention relates to eye glasses and particularly to the guardsthereof and has for its primary object to improve the construction,arrangement and operation of the parts in a simple and economical mannerwhereby the greatest advantages are obtained in the application of theglasses upon the wearer with positive retention in place and withconvenience and ease to the wearer.

A specific object of the invention is to provide an eye glass guardhaving two separate and distinct self adjusting pads, giving twodistinct holding contacts.

A further object of the invention is to provide an eye glass guardhaving upper and lower pivotal pads adapted to oscillate upon axesextending in difierent directions.

A further object of the invention is to provide an eye glass guardhaving an upper pad which oscillates on a horizontal axis and a lowerpad which oscillates on a vertical axis.

A further object of the invention is to provide an eye glass guardhaving an upper pad adapted to oscillate on a universal connection and alower pad adapted to oscillate on a vertical axis.

A further object of the invention is to provide an eye glass guardhaving an upper and a lower pad, each of which automatically adjustsitself separately to conform in the one case to the upper part of thenose and the other case to the bony structure thereof.

A further object of the invention is to provide an eye glass guardhaving an adjustable upper pad to hold the glasses from tilting forwardbut which only rocks in one direction.

A further object of the invention is to provide an eye glass guard witha pad adapted to swing on a vertical axis and to oscillate on a secondvertical axis.

A further object of the invention is to provide an eye glass guard inwhich are combined two separate automatically adjusting 5 partscontrolled by the movement of the lever of the finger piece mounting,said lever moving both pads together on a vertical axis, and each padbeing automatically adj ustable on an axis of its own.

With these objects in view the invention consists in the improvedconstruction, arrangement and combination of parts hereinafter fully andspecifically described and afterward particularly pointed out in theclaims.

In order that the construction and operation thereof may be readilycomprehended I have illustrated in the accompanying drawings an approvedembodiment of my invention, and will now proceed to specificallydescribe the same, in connection with said drawings, in which Figure 1represents, in front elevation, a pair of eye glasses embodying myinvention, the outer portion of the lenses being broken away. Fig. 2represents the same parts in plan view, Fig. 3 represents, inperspective, a complete finger piece guard with lever, detached from themountings, Fig. 4 shows the lower pad of a guard, and Figs. 5, 6 and 7illustrate means for adjusting the upper pad and means whereby my lowerpad may be applied to an ordinary eyeglass.

Like reference characters indicate the same parts wherever they occur inthe various figures of the drawings.

Referring specifically to the drawings, 8, 8, indicate the lenses, whichmay be of any desirable construction and which are con nected togetherby a bridge 9, said bridge being provided with ears 10 which encompassthe inner edges of the lenses and are secured by screws 11 which passthrough one wing of each fork and the lenses, and are threaded into theother wing of each fork in the usual manner. lhe bridge is furtherprovided with integral braces 12 which bear against the edges of thelenses and with fiat portions 13 respectively arranged at either end ofthe bridge and adjacent to the lenses, said flat portions formingbearings, upon which levers 14: are pivotally mounted by means of screwsor pins 15, said levers being actuated in the manner hereinafterdescribed by means of springs 16 coiled about the pivot and hearing atone end of each spring against the side edge of one of the braces and atthe opposite end of the spring, on the opposite side of the pivot,against the side of the lever, the tendency being such as to alwaysyieldingly hold the finger pieces 17, formed at the end of the levers,in the position shown in Fig. 2.

The constructions hereinbefore shown anddescribed are well known andform the base or foundation upon which the particular constructionsembodied in my invention are mounted and operated.

There is a lever 14 pivoted at each end of the bridge and each is of thesame construction. Each lever is twisted at 18 to change its horizontalposition at its pivotal point to a substantially vertical position, at.19 where it is, in the illustrated embodiment of Figs. 1, 2 and 3,bowed forward in a substantially horizontal plane into substantially Ushape, at the termination of which at 20 is formed the goose neck whichextends upwardandhorizontally to receive the upper pad 21, and downward,in the form of a sub stantially vertically depending spindle or axis,22, to receive the lowerpad 23, said lower pad being of substantiallyinverted pear shape and provided with an opening 24, the metal at theupper end of the opening and at the upper end of the pad, being bent atsubstantially right angles to the body of the pad to form ears 25 and 26having openings 27 .and 28, whereby the padmay be slipped upward on theaxis 20 so as to oscillate thereon, the split lower end 27 of said axisbeing spread, below the ear 25, to prevent the pad slipping ofl thespindle. The upper ends of the goose necks 20 are extended ,rearwardly,forming substantially horizontal arms 29, which terminate in tongues 30.Extending from the top and bottom sides, or edges, of the arms 29 areprongs 31 which are normally in the same plane as the arms 29 and are.of U shape, the outer ends being curved" backward and terminatingadjacent to the sides of the tongue 30 at or near the end thereof. I Themovable part, or pad proper, of the guard, is indicated at 32vconsisting of a front or face adapted to contact with the nose and apreferably metallic backing .38 secured thereto in any suitable manneras for instance, by pins or screws, 34 entering the holes in saidbacking, being bent to form a longitudinal flange 35 at substantially aright angle to the body of the pad.

To attach the arms 29' ofcthe guards, and

the pads 32, together, no extraneous fastening devices are necessary,the operation being as follows In thevnormal form of the arms 29 asdescribed, said arms being usually stamped out of suitable flat stock,with the U shaped fork prongs 31.and tongues 30 in the same plane withthe arms and, the tongues not extending beyond the prongs, said tongueswould be prevented fromentering oblong openings 36 made in flanges 35 toreceive said tongues, but when said prongs are bent substantially asshown in Fig. 7,the pads may be passed upon the tongues, the latterentering the openings 36 until the flanges are substantially contactingwith the prongs, adjacent to the tongues, when the prongs may be bentback again to substantially the plane of the tongues 30 and arm 29, asshown in Fig. 6. In these positions, the holes 36-being slightlylargerthan the tongues, the pads will be movable on the tongues as fulcra, andpermitted to swing on said tongues in substantially vertical andsubstantially horizontal planes, allowing them substantially universaladjustments, within reasonable bounds, to adapt themselves to variousnasal conformations and to insure proper contact therewith when pressedupon by the elasticity of the spring bow. To remove and replace'thepads, it will only be necessary to bend the prongs to the positionsshown in Fig. 7 when the flanges'may be freely slipped off thetongues.

In Fig. 6- the goose neck 20 is not used but an ordinary, plate 20 issubstituted," which carries the upper pad on its arms-29* and may besecured rigidly to the glasses by pins' or screws passing throughopenings 50, the vertical spindle or axis 22 to receive the lower pad25, projecting downward from its lower edge. a 7

From the foregoing it will'follow that I have provided eyeglasses withan upper having a substantially universal movement on axes atsubstantially right angles to' each 7 other and with a lower pad, havinga substantially vertical axis, which cooperates with the upper pad toclosely fit upon two 7 points on each side of the-nose and to ad justthe guard automatically upon various sizes and shapes of noses. I I

It will be obvious that my lower-padson their vertical axes may be usedwith advantage with upper pads not pivotally mounted.

, I desire it to be understood that my'invention may, as before stated,he applied to any form of eyeglasses comprising yieldingly pressed nosepads and that changes in the form, proportions and arrangement of thespecifically described parts may be made, without departing from thespirit and scope of the invention as defined in the appended claims. a xI I Having thus fully described my invention, what I claim as new anddesire to secure by Letters Patent of the United States is .1. Aneyeglass guard comprising a supporting element, and upper'and lower padsindependently and automatically adjustable on said element on axes at anangle to each other.

2. An eyeglass guard .comprisingapivoted supporting element, and padspivoted to said. supporting element above and below its pivot on axes atan angle to each other, said pads being independently and automaticallyadjustable on their pivots.

3. An eyeglass comprising lenses, a connecting bridge, a lever andfinger piece mounted to swing on said bridge, a padsupporting elementcarried by said lever, an upper pad mounted by a universal connection onsaid element, a vertical axis on the supporting element, and a lower padmounted to oscillate on said vertical axis.

4. An eyeglass comprising lenses, a connecting bridge, a lever and gerpiece mounted to swing on said bridge and a supporting element carriedby said lever, said supporting element carrying an upper pad mounted ona horizontal axis and a lower pad mounted on a vertical axis.

In testimony whereof I afiix my signature in presence of two witnesses.
